806 with D361. Engine oil keeps going overfull. We noticed this starting to happen this fall. It will get so full and thin that it will eventually pour out the blowby tube. We just kept changing the oil regularly to get us through. Originally we thought fuel was getting into the oil, but now I've convinced myself that it is Hytran making its way to the engine oil (any way to make certain it is hytran vs. diesel). If it is in fact hytran, where is the likely problem and how major of a fix are we talking? Also, am I playing Russian Roulette by continuing to run (changing the oil regularly) this tractor?

There is no possible way for hy-tran to be mixing with engine oil on an 806. You need new seals on your injection pump driveshaft.

If it is fuel from the injection pump, wouldn't I be able to see fuel coming from where the injection pump mounts to the engine? Are these seals a job for a pump shop or can I do them? Thanks guys.

It's a bit of a chore. Get yourself an I&T manual, read through the procedure for removing the injection pump and the pump drive adapter (assuming you have the Roosa-Master pump) and decide from there if you can do it. The seals are inside of the pump drive adapter, so the pump will not have to be sent to the pump shop. If your 806 has the old IH injection pump, I can't tell you what's all involved. I think the shaft stays with the pump on that one, so it might be a job for the pump shop.

Will I need to remove the pump drive shaft? Or can I just remove the pump adapter, replace the seals, reinstall the adapter over the shaft and be done? Thanks!

Okay guys, sorry to bother you again, but I'm stuck. I got the pump off, and was hoping I was going to be able to unbolt the adapter and slide it off the shaft but that doesn't appear to be the case. Do I have to unbolt the timing gear cover and the nut on the front of the pump shaft, then pull the drive shaft out and remove the adapter over the front of the shaft instead of the rear?

Yep, you'll need to push the driveshaft out of the gear, then the adapter will come off. There's a bearing at the rear of the driveshaft that prevents the adapter from being removed over the rear of the shaft.

 Okay, last question. Which way to the seals go? in reply to K.B.-826, 02-21-2008 15:40:26  
Alright guys, last question I promise. Which way do the two seals go? I THINK the one nearest the injection pump has the spring facing the injection pump. And the one nearest the engine, has the spring facing the engine. Is that correct? Thanks guys, you've been a big help.

You are correct. The spring side of the seal faces the oil you are trying to seal. In this case you need to seal both the engine oil and the diesel fuel so the seals need to be installed one facing forward and one facing the rear.

You can do it. You do need a shop manual for instructions. I can send you a page from one if you like . E-mail me if interested .

Bet it is fuel. Probably the seals on the injection pump drive shaft. Don't see any way for Hytran to get in the engine oil. DON'T run it.
